コーティングの方法は、刷毛塗り、ローラー塗り、フレキソコーター、メイヤーバー（ワイヤーバー）コーター、スプレィ塗り等の公知のコーティング方法で塗布する。
塗布後の乾燥は、熱風乾燥、遠赤外線乾燥等によって行われる。
なお、乾燥後にブラシ、サンドブラスト等によって、混合物層を粗面かすることも好ましく、それにより、焼成カルシウム粉末の表面が大量に露出されて抗菌・殺菌作用が大きくなる。 The lamination or coating of the mixture layer of the calcined calcium powder and the edible resin on the surface of the paper, cloth or resin film for manufacturing the bag body or the inner surface of the housing is usually formed by coating such as brush coating or spraying.
The mixture used for laminating or coating contains a calcined calcium powder, an edible resin and at least a solvent for the edible resin, usually water or alcohol.
The mixture for coating (for coating) is a coating liquid, which has a viscosity suitable for coating, and becomes a viscous liquid by dissolving an edible resin in water, for example.
The thickness should be 5 to 5000 μm (dry thickness).
The coating method is a known coating method such as brush coating, roller coating, flexographic coater, Mayer bar (wire bar) coater, and spray coating.
Drying after coating is performed by hot air drying, far infrared drying, or the like.
It is also preferable to roughen the mixture layer with a brush, sandblast, or the like after drying, whereby the surface of the calcined calcium powder is exposed in a large amount and the antibacterial and bactericidal action is enhanced.

In FIG. 3, 1B is a mixture layer, 20 is a plastic container, 20A is a lid, 20B is a stopper, and 30 grains.
(1) Preparation of coating mixture (coating agent) 8 parts by weight of carrageenan powder, 2 parts by weight of PVA (polyvinyl alcohol) powder and calcined calcium (Ca (OH) 2 ) powder (average particle size 20 μm) in 200 parts by weight of water. 20 parts by weight was added, and the mixture was stirred and mixed to prepare a viscous mixture.
Next, 50 parts by weight of calcined calcium (CaO) powder (average particle size 30 μm) was added to and mixed with the viscous mixture to obtain a viscous mixture (coating agent).
(2) The mixture (coating agent) was sprayed on the inner surface of the plastic container 20 shown in FIG. 3 with a spray gun and then dried with an infrared lamp to form a mixture layer 1B on the inner surface of the container 20.
The mixture layer 1B was also formed on the inner surface of the lid 20A of the container 20.
The grain (soybean) 30 was placed in the container 20 produced as described above and stored.
When soybeans stored at room temperature for 3 months were taken out by opening the stopper 20B and inspected, no putrefaction or mold formation was observed, and the material did not change at all.
